AR HIBALD KENNETH MAGLEAN, 0F OTTAWA, ONTARIO, CANADA.

GRAIN-CLEANER.

To all whom it may concern. I

Be it known that I, AROHIBALD KENNETH MAoLnAN, a subject of the King of Great Britain, a resident of the city of Ottawa, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Grain-Cleaners, of which the following is a specification. 7

This invention relates to improvements in graincleanersot thetype utilized by farmers for obtaining seed grain, and the objects of the invention are r to facilitate feeding stock to the machine and distributing it over the riddles andscreens in such'a manner that roughage and foreign" matter will be carried 01?, and the good grain in first and second or other grades and the tailings. will be recovered, to so control the feed of the stock that it can be adjusted during the operation of the machine, so that there is no possibility of flooding taking place, and the riddles or screens choked by too thick a layer of grain thereon.

Further objects are to so arrange the riddlesand screens that an air blast will be passed between the same,'over the surface of the screens and-through the riddles from the under side thereof so removingv dirt and other, foreign? matter, to provide a wind board which canbe adjusted to suit the conditions under which the machine'is working, and to transmit a reciprocatory motion to the riddles and screens. 1 1

Further objects are to provide a mechanical bagger which may be adjustably mounted on the front of the machine, and arranged in such a manner that, when it is out of commission, it may be rotated to lie along the 7 top of the machine so thatth'e machine will thus occupy a minimum of space when not in use, and will be capable of being readily transported from place to place by two men, one carrying each endofthe machine. If the bagger were made rigid and stationary one man could not span that endjof the ma,-

chine adjacent to the bagger, and it would require three mento move the machine and this is ofgreat drawback in practice.

Furtherobjects still are to; rovidefade quate head room betweenthe oor and the discharge end of the bagger, to provide means whereby a plurality. of bags may be positioned and successively filled with good grain, and also to provide means whereby the tailings may be bagged at the opposite end of the machine to the good grain and Specification of Letters Patent.

simultaneously with the bagging of the good With the above and other objects in view my invention consistsessentially of the improved construction hereinafter described and set forth in the followingspecification and accompanying drawings forming part of the same.

In the drawings: I Figure l is a side elevation of the improved grain cleaner.

Fig. 2 is a longitudinal section ofthe same. Fig.3 is a transverse section of the throat of the bagger.

' Fig. 4 is a fragmentary side'elevation of the adjustable bearing on the upper end of the bagger.

Like characters of reference refer to the like parts in; thes'everal figures.

Referring; to the drawings,A represents the improved graincleaner comprising a spaced relation.- v At one end of theframe and extending frame 10 carryingside members 11 held in transversely across the same a fan 12 is provided, thesai'd fan being. housed in a casing "13 having a discharge opening 14, and above this fan and extending rearwardly thereof as hopper 15, the lower .walls of which converge. The rear wall 16-is slidable and provided with a rack 17 adapted to mesh with a gear 18 which is rigidly mounted on a spindle desi ternally of tile machine, to move the wall 16 rearwardly and sop'rovide an adequate openned to be manually rotated GX- ing at the lowerendofthe hopper to discharge stock into the machine. Below the hopper a shoel19 is provided and suspended from, links 20 pivotally con nectedto theside members of the machine,

and'22 from the'former of which screens 23 are,supported,. the screens being angularl-y disposed, the front end :resting on trans-o versely extending bars 24.

hold thescreens in place during the 'recipro-' cation of the shoes andthis shoe is provided with brackets 21 The rear end of the riddle is supported "on the bracket 22 while the front end is frict-i'onally embraced by the sidewalls of the shoe .19, being held in positionpby suitable tensioning". bolts extending transversely across the shoe theihead .of, t hi s bolt being designed to lie within the enlarged orifice 26 provided in the side wall of the machine.

The riddle 25 slopes downwardly to the rear of the machine while the screens 23 slope downwardly from the rear to the front end of the machine, and at the rear of the shoe a wind board 27 is pivotally mounted in alinement with the screens 23 and the riddle 25.

A distributing feed board 7 is slidably carried by the shoe and located below the discharge end of the hopper 15 and the shoe is provided with a transversely extending bar 28 connected through a link 29 with a pivotedlever 30, one end of which extends through the slot 31. in one of the side members 11 of the machine, and this lever is connected by the rod 32 with a pitman 33 on the driving sprocket 34 of the fan shaft.

At the front end of the machine and in alinement with the upper screen 23 a discharge chute 35 is provided, designed to receive the good grain from the said upper screen, and the lower screen 23 communicates with a discharge chute 36 discharging below the machine.

At the rear end of the machine a discharge chute 37 is provided to which hooks 38 are attached to permit of a bag-being secured for filling purposes. 7

A drawer 39 is located below the screens 23, and inclined boards 40 and.41 bridge the gaps between the chutes 37 and 36 and the drawer 39 respectively, so that all light grain or tailings passing throughboth screens 23 will be delivered to and collected in the said drawer.

- The bagger B which is located in the front end of the machineconsists of a casing 42 provided at the upper end of the front wall with a discharge conduit or throat 43, which is downwardly disposed and provided with two discharge openings .44 above which a flap valve 45 is pivotally mounted, so that by rotating this flap valve to either side of the throat either of these'discharge openings may be brought into operation.

Hooks are provided from which bags may be hung to inclose the mouths of these openings, and these bags may be secured with extended or open mouths and suspended by the hook 47, secured to the side strap 48 of the casing of the bagger.

In the bagger an elevator conveyer 49 is operably mounted, and the upper spindle of this elevator conveyer is provided with a sprocket 50 connected by a chain 51 with the sprocket 34 of the fan shaft, so that on rotation of the fan shaft motion will be trans mitted to the elevator conveyer.

This elevator conveyer consists of an endless chain 52 with buckets 53 thereon, and the good grain from the separator is delivered to the chute 54 into the casing 42, and during the rotation of the elevator conveyer the grain is lifted and delivered into the throat of the casing and discharged through one of the openings 44 to the bags.

This bagger is held in position in such a manner that the weight rests upon a transversely extending bar 55 located in front of the fan casing 13, and the end of the side straps 48 adjacent to the casing are cut curvilinearly so that while providing a broad bearing surface to a bar 55, they will be clear of the fan casing.

The casing 42 is connected through links or rods 56 which are pivotally connected at one end to the side bars 48 of the baggei casing 42, and at the other end of the side members 11 of the grain cleaner, and the upper end of the casing is connected through links or rods 57 which are pivotally attached at one end to the side walls of the casing 48, and at the other end to the side walls 11 of the frame 10 of the grain cleaner.

The upper spindle of the elevator conveyer is journaled in an adjustable bearing 58 as shown in Fig. 4, and by swinging this bracket about the pivotal'point 59 and engaging one of the orifices 60 with the bolt 61 extending through the side wall of the casing, then the chain 52 may be tensioned or slackened off as is found desirable.

When the machine is not in use the mechanical bagger is rotated into the position indicated by the dotted lines in Fig. 1, so that the machine will occupy a minimum of floor space and will be easily gotten at to carry or transport from one place to another, when such is found necessary or desirable. \Vind boards 62 are provided on the side walls 16 of the machine to control the supply of air to the fan.

When this machine is in use the stock'is delivered to the hopper 15, and the wall 16 is adjusted to allow the desired amount of stock to be delivered to the adjustable feed board 7 and, on rotation of the fan shaft, the shoe 19 will be oscillated by the rod 32, and the grain will be shaken on to the riddle 25, where it will meet with the air passing through the riddle, and the light dirt and foreign material will be blown off over the wind board 27, and any husks or heavier foreign substance will impinge on the wind board 27 and be delivered to the chute 37, and bagged. The good grain and tailings pass through the riddle 25 to the screens 23 and the large grain will gravitate down the upper screen into the chutes 35 and 54, and so into the casing 42 of the bagger.

- The second size good grain will have passed to the lower screen 23 and be delivered to the discharge chute 36.

Any tailings will pass through 23 and be delivered into thedrawer 39.

the screens During the reciprocation of the fan and lifted by the bracket 53 and carried up and discharged into the conduit 43 or throat Where it will be delivered to one of the discharge openings 4:4: from which the bags are suspended.

When one bag is filled the flap valve 45 is rotated to the opposite side of the throat to allow the second bag to be filled.

When the machine is out of commission the mechanical bagger B is rotated from the front of the machine to the top thereof, so that the casing will occupy the position shown in dotted lines in F ig. 1.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention, within the scope of the claim, constructed without departing'from the spirit or scope thereof, it is intended that all matter contained in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

A material delivering means comprising a mechanical bagger, straps on the side Walls of the bagger, and projecting beyond the rear face to coact with an abutment member, links pivotally connected at one end to the straps, links pivotally connected at one end to the side of thebagger adjacent to the top, a spout on the bagger, and means for attaching a bag to the spout, as and for the purpose specified.
